But Alyson Hannigan looked rather sprightly on her way to a Pilates session today, as well as trimmer.

The American Pie star, who gave birth to her second child in May, was seen wearing a long purple vest over black leggings, while armed with a flask of water and trainers ready for her workout.

Keeping trim: Alyson Hannigan appears to be on her quest to shrinking as she headed to Pilates in Brentwood

While there is a temptation to hide
beneath oversized clothing after putting on weight, it can often have
the opposite effect and make the person in question look bigger.

But Alyson looked petite in her quirky singlet, which cheekily exposed the frill of her black lace bra.

And despite getting ready to sweat
out her toxins and shift the pounds, the redhead appeared in high
spirits as she offered a smile to photographers in Brentwood,
California, from beneath her shades.

Changing shapes: Alyson looks svelte compared to during her pregnancy

Earlier this month, the comedic actress tweeted: 'I’m the right weight, just the wrong height.'

Alyson, who wed fellow actor Alexis
Denisof in October 2003, has two mini-me daughters in the guise of
three-year-old Satyana, and the latest addition to the family, newborn
Keeva.

Last September, around the time she fell pregnant, Alyson appeared to be gaining a little weight.

However, she strongly denied she was expecting a second child at the time and blamed her changing body on not doing enough exercise and indulging too much on the wrong foods.

She tweeted: 'NO, I’m not pregnant! I just ate too much carnival food, that time of the month, hurt my back & couldn’t suck my gut in, and need to do cardio! And I’m NEVER gonna wear that shirt again!!'
